... Pulverulent material such as ammonium sulphate and sodium hexametaphosphate, is agglomerated by continuously dispersing the material so as to fluidize the particles of the material and form a fluidized bed in which the particles are dispersed and suspended in intimate relationship and make repeated contact with one another, maintaining the material within the confines of the bed while moving the bed over a supporting medium, and subjecting the fluidized particles of at least a part of the moving bed to a condition changing agent, such as the condensation from superheated vapour or vapour-gas mixture, so as to form adhesive agglomerating surfaces on the particles and thereby effect the agglomeration. The preferred procedure is depicted in Fig. 4. Dry pulverulent material from a hopper 10, Fig. 2, is kept in a fluidized state as it moves over 60-400 mesh glass cloth screens 16, 18, 19 and 20 by the circulation of gaseous media as follows: air at room ...

Spherical balls, notably microballs of welding alloys, are produced by passing a melted material through vibrating orifices (8) of a granulation pot (4), in order to form droplets which solidify when falling, by gravity, into a cooling tower (16) filled with an inert gas. To improve the surface condition of the balls, the inert gas comprises approximately 15 to 150 ppm of oxygen. Moreover, the melted material is subject to ultrasound stirring (21, 22) just before being fed into the granulation pot. The balls are, preferably, dampened at the outlet of the cooling tower by brushes (25) composed of polyamide wires. Besides, the control of the vibration frequency of the vibrating orifices in relation to the percentage of balls meeting the standards enables to improve the output.

The present invention utilizes a high-speed intensive mixer in fluidizing type solid phase neutralization reactor to blend solid state alkali hydroxide with any humic acid sources. The final product is a dry humic acid salt. The purpose of this innovative method is to eliminate a series of complicated unit operations commonly employed by the traditional process. These removed steps may include dissolving caustic soda, mixing in a paste like formation, extrusion, granulation, drying, and grinding, etc. The new invention contributes to a simplified flowsheet, resulting in sharply reduced equipment investment, the required plant space, and labor and energy costs. All these factors coupled with increased productivity will drastically lower the overall production cost. Also the reduction of dust pollution will greatly minimize the impact in environmental protection and safety issues. 1.

Принадлежит: Northeastern University Boston

A process for producing spherical polymer particles which may be either monodisperse of a predetermined and controlled size, or polydisperse, using a liquid atomization technique. The process includes an aerosol generator to create a stream or multiple streams of liquid droplets sprayed into a thermal reactor. The aerosol generator sprays the feed solution which comprises liquid organic monomers or semi-polymerized monomers, a polymerization catalyst and optionally, a solvent, into the thermal reactor environment. The solvent evaporates allowing polymerization reactions to commence. Polymerization may proceed by a variety of methods. Polymerization is completed during the flight-time of the droplets and the solid polymer particles are collected at the bottom of the reactor. The size of the particles in every batch may be predetermined and controlled by fine tuning the aerosol generator's configuration or operational parameters to adjust the size of the droplets of the feed solution being sprayed into the reactor. In one variation, the feed solution to the aerosol generator may be a polymer dissolved in an appropriate solvent. The aerosol generator then sprays the polymer solution in the thermal reactor to generate particles by evaporating the solvent.

Method and device for drop generation with simulated granulometric spectrum

Номер: RU2562488C2

FIELD: process engineering. SUBSTANCE: invention relates to drops generation and can be used for synthesis of balls (or spheroids) of nuclear fuel materials. In this process fluid jets are forced to collide with substrate at preset relative velocity to develop vibrations in substrate in at least one vibration frequency. Besides, said substrate is heated to collision temperature whereat liquid film produce in collision and subjected to vibration is heated to main temperature for combination formation of main drops from said film. Then, drops are displaced through the system of transfer/deceleration/sorting in direction of the main drops fluid deposition. Displacement is performed at displacement temperature. Set of parameters is used including relative velocity of collision, vibration frequency, main temperature and displacement temperature and grain size of formed main drops is simulated as well as their velocity. Invention covers also the device for described process implementation. EFFECT: drops generation brought about by disintegration of thick fluids, application of settling or other phenomena, expanded range of grain sizes. 28 cl, 14 dwg, 2 tbl РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 562 488 C2 (51) МПК B01J 2/02 (2006.01) B05B 17/04 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ 2013131027/05, 29.11.2011 (24) Дата начала отсчета срока действия патента: 29.11.2011 (72) Автор(ы): БРОТЬЕ Мериль (FR), МУЛИНЬЕ Доминик (FR) 08.12.2010 FR 1060233 (43) Дата публикации заявки: 20.01.2015 Бюл. № 2 R U (73) Патентообладатель(и): КОММИССАРИАТ А Л'ЭНЕРЖИ АТОМИК Э О ЭНЕРЖИ АЛЬТЕРНАТИВ (FR) Приоритет(ы): (30) Конвенционный приоритет: (45) Опубликовано: 10.09.2015 Бюл. № 25 C 2 C 2 (85) Дата начала рассмотрения заявки PCT на национальной фазе: 08.07.2013 (86) Заявка PCT: 2 5 6 2 4 8 8 EP 2011/071297 (29.11.2011) R U 2 5 6 2 4 8 8 (56) Список документов, цитированных в отчете о поиске: FR 1541739 A, 11.10. ...
